Why does the GFCI breaker keep tripping immediately?

The GFCI breaker may be tripping immediately due to a ground fault, which means there is a problem with the electrical wiring or a connected device that is causing electricity to flow where it shouldn't. This can be a safety hazard and the GFCI breaker is designed to trip to prevent electrical shocks or fires. It is important to identify and fix the issue causing the ground fault to prevent further tripping of the breaker.
